This option is very useful if you are cruising and want to motor when you are too slow. You can set up the sailing speed over ground limit under which you want to start your engine and the motoring speed when started.
To highlight those isochrones where the boat is motoring, we draw the best route with a dotted line.
Here is an example for a planned trip between Malta and Sicilia on March 28, 2013 on a first 31.7. It takes more than 54 hours if you sail all along. If you decide to motor at 7 knots when your speed is less than 4 knots, then the trip lasts around 48 hours and you motor for 18 hours. Is it worth it?
Note that when the boat is powered, she does not necessarily go straight towards the finish point. She can go for the wind by extending the route.
